II During his 30 years supervising inmates in St. Petersburg's notorious Kresty Prison, Baldaev recorded over 3,000 of their tattoos and parsed their meaning, revealing an extraordinary world where the criminal's position, history and even sexual preference are displayed indelibly on his body, and that marked body serves as a passport into the underworld.
